This is one of my favorite weeknight dinners because it comes together in just 40 minutes from start to table. Swordfish is a wonderfully meaty fish that holds up beautifully to roasting, and it's packed with omega 3 fatty acids that are great for your heart. The green beans add a bright, fresh contrast, while the lemon butter sauce ties everything together with such elegance. It feels fancy enough for guests but honestly requires nothing more than basic kitchen skills. Simple, healthy, and absolutely delicious.

Instructions
- 1
Preheat your oven to 425°F. Toss the trimmed green beans with 2 tbsp olive oil, half the minced garlic, salt, and pepper on a baking sheet, spreading them in a single layer.
Tip: Ensure the beans are dry for better roasting and crispiness.
- 2
Place the green beans in the oven and roast for 15-18 minutes, stirring halfway through, until they're tender with slightly charred edges.
- 3
While the beans roast, season both sides of the swordfish steaks generously with salt and pepper. Let them sit at room temperature for 5 minutes.
Tip: Room temperature fish cooks more evenly throughout.
- 4
Heat 2 tbsp olive oil in a large oven-safe skillet over medium-high heat until shimmering. Sear the swordfish for 3-4 minutes per side until golden brown, then transfer the skillet to the oven.
Tip: Don't move the fish while searing to develop a proper crust.
- 5
Roast the swordfish in the oven for 6-8 minutes until cooked through and flaky when tested with a fork.
Tip: Swordfish is best served medium, so avoid overcooking.
- 6
Remove the skillet from the oven and transfer the swordfish to a warm plate. Add sliced shallot to the pan over medium heat and sauté for 1 minute until fragrant.
- 7
Pour in the white wine and scrape up any browned bits from the bottom of the skillet. Let it reduce by half, about 2 minutes.
Tip: This builds flavor from the fond left by the seared fish.
- 8
Remove from heat and whisk in the cold butter pieces until the sauce is silky and emulsified. Stir in lemon juice and zest, then taste and adjust seasoning.
Tip: Adding cold butter at the end creates a luxurious, restaurant-quality sauce.
- 9
Divide the roasted green beans among four plates, top each with a swordfish steak, and spoon the lemon butter sauce over and around. Garnish with fresh thyme sprigs and additional lemon zest.
